The temperature in the cabinet is now 17 degrees and things are not staying frozen. The bottom drawers are fine and things stay frozen in them and the ice maker is making ice and the ice isn't melting hardly at all.

Re: sub Zero isn't cold enough
Sounds like it might just be a simple as a dirty coil. Use a coil brush (you can get at homedepot)
Clean the dust and from the back and bottom of the fridge. The coils pickup alot of dust over time making the fridge become ineffecent. One some subzero units your condenser coils are on top. Use the brush in conjuction with the vacuum to get it clean and watch your fridge for a hours to see if that helps before you call a repair tech out. Make sure you unplug the fridge when your doing this.

The temperature in the freezer is not at zero degrees or less. Maybe the freezer door is open for too long a time. There may be a problem with refrigeration system not getting cold enough due to numerous problems.
More thatn likely, being thats an older model, you are low on freom and the temperature isn't cold enough for the icemaker to keep constant production up. You maybe thinking the freezer is fine because stuff is frozen in there but that is why most people don't catch the problem until they lose all their food. The temperature for the icemaker to even come on is 10 degrees F. The sub zero freezer temperature should be around 0. Check your settings and make sure they are turned down but I would get a thermometer and put in the freezer and check to see what it says. If its above 5 degrees F check your condensor coils to make sure they are clean and also see it the condensor fan is running. If dirty, clean the coils and see if the temperature drops, if not call a service company.
The air door "cold control" may be obstructed or the air return may be obstructed. The air return takes the air from the refrigerator section and delivers it to the coil. It must be clear for the fridge to operate properly. The cold control is just a door flap that opens and closes and allows cold air to enter that part of the cabinet. Open the cold control more and see if that helps. You should feel more cold air coming from it. If you don't then there's an obstruction. If you have a thermometer that goes below zero, place it in the freezer. It should read 0 to -5 degrees f. If it doesn't then there may be another problem.
You probably need to defrost freezer - frozen moisture possibly stockedevap. fan motor in the freezer. Turn it OFF for 24 hours and start itover. Make sure no moisture condensation on the freezer compartmentsurfaces as walls and shelfs. If so wipe it out. Pull out and remove upper basket from the freezer, push fan switch which is located almost under ice maker.You have to hear evaporator fan motor start working. Still not work? Call to professionaltechie! Good luck! :)
Hello. You need a new cabinet thermistor and while you are at it replace the evaporator thermistor. (The evaporator is the cooling coil behind the back wall of your fresh food section) . These sense the temperature in your frig. Both of them are behind the back wall of your fresh food compartment. You will need a wire crimper and a heat gun or lighter to heat shrink the wire connectors that come with the new ones.
I have seen this situation the fridge had to be rolled or pulled out far enough that the door then can be swung open more and for the door bins had to be taken off to get the crisper out. But if you have a Sub Zero that can be a problem!
